Load properties into a subsequence using 2016 property loader

Hi all,

I am looking to load properties into a subsequence that is called multiple times. I would like to load *different* parameters into each instance of the subsequence. I have attached how I would do this using the previous version of the Property Loader--I pass a parameter to each subsequence call to tell it what its section of the property file it should reference, then use the Start and End tokens to identify individual sections. 

My question is, how can I do something similar using the new 2016 property loader? I know I can still use the legacy property loader, but going forward I would like to have a strategy that works with the new property loader that natively supports import/export from the GUI. 

Thanks,
